This invention relates particularly to a power driven apparatus atively mounted on. a press the purpose of'squeezing An object of the invention is'to provide a that can be mounted power driven apparatus on the threaded shaft of of fruit press to take. the

work of the hand used for pressing fruits.

A further object of provide a adapted to be operto beused for a conventional form the invention is to self-contained pressing -11I1lt having an electric motor connected with a suitable gear train operatively mounted on the threaded shaft of a conventionaltype of fruit press and by means of the motor and gearing the pressing unit is moved into contact with the fruit during the pressing operation and withdrawn from the pressed fruit after the completion of the pressing oper-' ation.

Other objects of the inventionare to provide a power driven fruit pressing mechanism which consists of able selective speed gear a motor and a suittransmission, comprising an apparatus that will be superior in polnt of simplicity,

inexpensiveness of construction, positiveiiess of operation, and facility and convenience inuse and general efficiency. 7 In this specification drawings, the invention and -tl1e annexed is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may beembodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it In the accompanying ings: v

place of and do the. operated appliances now structure is. positioned. The base of the press is provided with a threaded shaft fixedly arranged centrally thereon. and a pressing collar is mounted on the'upper end of the threaded shaft to be moved up or down on the said shaft manually, by means of suitable levers; In the reverse'case the in a rapid-and effective manner.

In detail, the construction illustrated in the drawings comprises a fruit press base 1 4;) having a'flange 2 arranged centralin which a threaded shaft 3 is fixedly positioned.- A drum 4, is formed ofly thereon,

a plurality of separated slats or staves which ratus, to accomplish the pressing of thefruitare'located on their ends around the thread l ed shaft 3; The fruit tobe pressed is placed within the drum 4 on the upper face of the base 1 and around the threaded shaft 3. The power driven apparatus, which-is mounted on the threaded shaft for pressing the fruit,

consists of a'pair of plates and 6 held together in spaced parallel relation by, the spacing shafts7. Aninternally threaded collar 8 is revolubly journaled at its oppositeends 9 and, 10in the respective plates!) and 6 of the frame, and between the lower end of the collar 10 and the plate 6 'asuit ablei'thrust bearing 11 is interposed. The

collar 8 is threadedly engaged with the] shaft 3 and supports the plates Sand 6 on the shaft 3.. A gear 12 is mounted on the collar 8 and said gear 12 is enmeshed with a reducing speed gear train generally designated by the numeral 13. i

' A motor 14 is posi said motor is provided with a bevelled gear 15 on the/armature shaft thereof. The

bevelled gear 15 meshes with a bevelled gear 16 which is fixed'on journaled in bearings. 18 and 19 secured on the plate 6. "A pair'of connected gears 20 and 21 are fixed on the shaft 17 so as to turn tioned on the plate 6 and a shaft 17 rotatively said gears on the shaft 25 and movement of the collar 8 advances therewith. The and 21 are adapted to be meshed interchangeably with the respective change-speed gears 22 and 23 movably held on the worm shaft 24, which is revolubly mounted in bearings 25 secured to the under face of the plate 5. A set screw 26 is arranged in the drum connecting the change-speed gears 22; and 23 for locating bringing the same into engagement with either of the respective gears 20 and 21. i

A worm 27 is fizied on the end of the worm shaft 24 and meshes with a worm gear 28 in the train 13.

An electric switch 29 is provided on the plate 6 to control the flow of electrical energy into the motor 14 and to regulate the movement thereof. The switch 29 is a two-way switch so that the direction of movement of the motor armature may be controlled for the ruu'pose of moving the gear train 13 in a clockwise or counterclockwise direction.

A fruit press constructed in accordance with my invention would be operated in the following manner: The collar 8 and the frames 5 and 6 with the other mechanism thereon would be positioneu on the threaded shaft 3. The motor 14 would be energized and the rotative movement thereof transmitted through the change speed gearing 13 to the collar 8 which, would advance relative to the fixed shaft 3 and the relatively immovable frame members 5 and 6, I 'Rotative the lower frame 6 into contact with a pressure plate 30, placed on top of the fruit to be pressed. The friction created between the plate 6 and pressure plate 30 is sufficient to prevent the frame mechanism from turi'ring relative thereto, and constant rotation of the collar 8 causes the mechanism to be advanced downwardly on the fruit to press or squeeze the juices therefrom. Themotor driven gearing thus effectively performs the same squeezing operation on the fruit that has heretofore been accomplished through manual effort. By the use of my mechanism, one man may handle the entire pressing operation, whereas, by the use of the conventional hand power mechanism the services of two or three individuals are required. After the fruit has 'mesln'ng with said worm been squeezed so that substantially nomore juice remains there-in, the motor '14 is reversed and the squeezing frames 5 and 6 withdrawn from contact with the fruit, permitting-the squeezed mass to be withdrawn from the drum at and the same charged with a fresh supply of fruit. Having thus described this invention, what I now claim and desire to secure by Letters Patent is: i

1. A device of the character described comprising a drum; a threaded shaft extending upwardly from said drum; a collar threaded on said shaft; a base plate secured to said collar a reducing speed gear train, a gear mounted on the collar said. gear meshing with said reducing speed gear train mounted on said base plate; a worm shaft, a shaft journaledon said base plate; connected driving gears fixed on the shaft, change of sp rd gears shaft, a worm on the end of the worm shaft; a worm gear in the gear gear, and a reversible motor for driving said first mentioned shaft to cause said collar and, base plate to descend upon said threaded shaft.

2. A device of the character described comp inga central threaded shaft; a spool shaped frame having a threaded. collar mounted on said shaft, said threaded collar having threaded engagement with said shaft, said frame having a base plate; a shaft journaled on said base plate; a pair of connected gears on said shaft; a worm shaft, mounted on said base plate having a worm on one end; a drive connected change of speed gears on said worm shaft adapted to selectively mesh with said first mentioned gears; aset screw for fixing said last mentioned gears; a train of reduction gears mounted on said base plate with which said worm has engagement and a gear on said collar meshing with said reduction gears; and means for causing said first mentioned shaft on said base plate to rotate said frame'on said first mentioned central shaft. I

In testimony whereof, I have hereunto set my hand at San Francisco, California, this 17thday of July, 1925.
